The present invention relates to improvements in ice skates for affording a greater range of-skating action as compared with theV Xed runner skates commonly limited to straight-line movements over the ice. Y

The objects of the invention include means for detachably'mounting upon the fixed runner of a skate an attachment runner adapted f for use in fancy or curved-line skating, and

' 10 also-include the provision of means for quick- Figure 1 of the drawing isa side eleva-v tional view embodying my invention, the attachment runner being shown in locked'relation with the fixed runner of the skate and in position for fancy skating.

Figure 2 is a side elevational view of a Xed runner speed skate, the attachment runner being removed therefrom.

Figure 3 is an enlarged side elevational view of the rear end of the skate taken in` part on the joint-line 3-3 of Fig. and showing means for locking the runners together.V Figure 4'is an assembled end view of the two-part locking lever. v

Figure 5 is a transverse sectional view on line 5-5 of Fig. 2, showing the lateral connection between'the runners. Y A Figure 6 is a transverse sectional view of Vthe detachable runner taken on line 6 6 of Fig. 8. I Y

Numeral 10 of the drawing designates the frame of the skate having the upright legs 11 provided at their upper ends with the sole plates 12 adapted to be secured in the usual manner to the shoes of the skater. At its lower end the frame is formed with a flange 13 iXedly secured by rivets to the main runfner 14, the latter being of relatively narrow 192s. serial No. 275,812.

thickness provided with a conventional running face, transversely shaped either straight or concaved, and adaptedV more particularly for straight line high speed work with a limited range of curving action. Atits forward endv the fixed runner 14 is formed with an upwardlyA extending leg 14a fixed to theV Y forward sole plate 12 and at its lower forward end a lock member 15 is formed, the rearward end of the runner being provided with a cam section 16. r

The attachment runner indicated by 17 is provided with 2a longitudinal groove 18 arranged to receive for lateralY support the fixedr runner 14, a transversely extendingV pin 19 being lherein shown as passing through .the forward end of runner 17 and engaging the lock member 15 of the fixedv runner 14. AtV its rearward end the grooved attachment runner 17 is provided with perforations 20 eX- A tending through the sidel walls; thereof on opposite sides of the groove (see Fig. 6). n A two-part look lever 21 serves to hold the runners together, the parts thereof having at their lower ends pivot hubs 22 which engage the perforations 20 of the'attachment runner wherein the lever is free to turn. An integral spacing block 23 is formed on one of the lever parts and on opposite sides of the block screws 24 and 25 extend through and secure theY sectionsof the lever together, conknection spaces 23a being formed on opposite Y sides of the block through which* the screws pass. link 26 is mounted in the connection space upon the screw'24, and upon the screw 25 a friction roller27 is carriedthat engages the .cam section 16 formed on the fixed runner 14,-the engagingface of the cam being disposed eccentrically withrespect to the pivotal axis-of the lever 21. Y Y

' In its 'forward or locking movement, the roller of the lever rides over the face of the cam section, and urges engagement between the bottom wall of the grooved attachment Vrunner 17 and the running face of the liXed runner"14 for detachably securing the two runners together, the forward movement of the lever in its engagement with the cam section also serving to lforce engagement be- At the upper end of the lever 21 a tween the interlocking members at the leading ends of the runners, thus effecting a double locking action-by a single forward movement of the lever.-

For operating and retaining the lever inv locked position, the link 26 thereof is provided with a slot 28 through which a Vstrap 29 is looped and passed around the adjacent Vrearward leg l1 of the frame l0, a strapbuckle 30 serving to hold the lever in a locked position.

The attachment runner 1i' may be quickly detached from the Xed runner by releasing the strap 29 and outwardly turning thelever I 2l and in which movementthe roller 27 will run free of the cam section V 16, and the iXed.

runner 14 urged loutwardly `from the slot in the attachment runner bythe rotary action of the pin 3l eccentrically projecting from the inner face of one of the pivot hubs 22, (see Figs. 3 and 4) the. free end of the pin being herein shown as abutting the. face of the opposite pivot hub and serving also as a spacer between the parts of thelever and receive the tension ofthe-connectionscrew 25.'

As thus constructed'the skate may be'readf ilyconverted either for speed -.or fancy skating, for the latter purpose the working face of the attachment runnerbeing. .relatively wide and conforming substantially with the Width in common use.
